" ENGINE-OILING- svs'rnm. j

To all. whom it may concern:

Be it known that I, ERNEs'r a citizen of the United States, residing In Arizona, have invented Globe, Gila county,

certain Improvements in Engine- Oiling Systems, of which the following is a specifi-' cation.

'One objectof my invention is to provide a novel arrangement and construction of containers and conductors especially adapt-- ed for use in the crank case of an internal combustlon or other form of cally cause an increased body of lubricant to be collected and put in active circulation at the points where it is supplied to the vcranks of the engine; the idea being to render larger bodies of lubricant available at such times as the engine is doing more than? .its normal amount of WOl'k and incidentally islongitudinally inclined in either or hot f two. directions.

Another object of the invention is to pro-- vide a novel form of lubricant container for I use in connection with the crank of an engine, whereby a greater. quantity of lubricant is automatically supplied to the crank whenever the engine and therefore the crank caseand attached parts are tilted in either of two directions beyond a predetermined amount. There 'is thus secured an ample supply of lubricant regardless of whether the front of said pressed.

These objects and other advantageous ends I secure as hereinafter set forth, reference being had to the accompanying drawings, in which Figure 1, is a longitudinal vertical section of the crank case of an engine, illustrating my invention as applied thereto; Fig. 2, is a transverse vertical section of the crank case taken on the line a-iz, Fig. 1, and Figs. 3 and-4, are fragmentary transverse vertical sections illustrating modified -forms of the auxiliary oil container.

In the above drawings 1 represents a casting constituting the lower portion of a; present instance designed in connection with-a four cylinderengine The crank shaftofthis engine is illustrated-at 2; and ithas; connected to ber-- tain of its cranks 3,4 and 5 the rods 6,--7' and -8.g Each ofthej connecting rods crank case in the for use it-alners are integral parts engine, where-- by the longitudinal inclination ofthe ap-' .-parati 1s in eitherdirection shall automatiengine be elevated or de connecting Specification of Letters Patent.

is provided with a downwardly extending projection 9 designed to periodically enter an auxiliary oil reservoir hereafter described for the purpose of collecting and delivering to the parts to which it is attached the lubricant necessary to maintain it in proper operative condition. With this idea in view, there is provided under each crank a basin-like container 10; it being noted that in the case illustrated all of said conof a single casting, although in some cases they may be made as separate units without departing from my invention. Below these containersthe crank case is continued downwardly to form a main oil reservoir 11 which extends underneath all of the auxiliar containers 10 and has conn'ected to its lower portion theintake of a pump 12 operated from any suitable part of the engine. The outlet conduit 13 of the pump is connected to a conduit 14 extending longitudinally of the crankcase and having an outlet indicated in dotted lines at 15 opening into each of the auxiliary containers 10. These latter each have a central transversely extending depression or cavity 16 designed to receive the' projection 9 .of the connecting rod to be supplied with lubricant from that particular container, and as shown, the bottoms of each container 10 are inclined downwardly toward its transverse cavity. Each of these latter has an outlet 17 communicating with a passage 18 consti tuting a level maintaining trap which passes under it and side thereof opposite that intowhich the outlet 17 opens. Adjacent said outlet 17 the passage 18 has an opening or passage 20 extending upwardly through the bottom of its auxiliary container, so that there is free admission of air to this end of the passage independently of the outlet 17 of'the cavity 16.

Under operating conditions, the main 'reservoir 11 is filled with oil, preferably to the level shown and the operation of the pump 12 causes this oil to be delivered to the various auxiliary containers or reservoirs 10,- which are filled thereby to a level ordinarily determined by the heightof the outlet-- opening 19- of the passage 18. 'As shown in-Eig. 1, the arrangement is such that under these conditions there is a body of oil in-each'eavity 16 and also in each paspage 18,-se that as the connecting rods 6- alternately enter and leave the lower part of the crank' case, their projections 9 scoop up or otherwise distribute a certain amount of lubricant from the depressions 16 in the desired manner. If new the engine to which the crank case is attached be tilted so that the center line of the crank shaft occupies the position indicated in dotted lines at w-w, then it is obvious that while the outlets 19 are all lowered, the depressions 16 each collect a body of oil greater than that normally in them, since each outlet 17 is raised. As a result the various projections 9 enter larg'er bodies of oil so that correspondingly increased amounts thereof are delivered by said projections to the parts requiring lubrication. As soon as the engine is returned to its level or normal position and consequently operates under normal conditions, the surplus liquid within the cavities 16 immediately passes through the outlet 17 and channel 18, overflowing at 19 into the main reservoir. On the other hand, if the crank case were so inclined that the line of the crank shaft occupied the position indicated by the line g -,g there would again be provided an increased depth of oil in the depressions or cavities 16, for while the outlet 17 would be lowered, the final outlets 19 would be raised. The auxiliary reservoirs thus retain the desired larger body of lubricant which is delivered by the projections 9, in the ordinary manner, to the parts requiring lubrication. As before, the return of the engine to its normal level at once permits the surplus lubricant in the auxiliary containers to be discharged into the main container 11 on account of'the lowering of the outlets l9, and it is noted that the siphoning-out of lubricant from the auxiliary containers is prevented by the air passages 20 which open into the passages 18.

By means of the construction above described increased amounts of lubricant are automatically supplied to the engine whenever the latter is longitudinally inclined in.

either direction and this is particularly advantageous since, especially in marine work, such inclination would ordinarily result in or be consequent-upon such an action of the engine as would require increased lubrication.

In some instances the auxiliary containers may be given the form shown in Fig 8, having their depressions 16 made with concave instead of perpendicularwalls and cut away at one side so that the outlet 17 and the air passage 20 are replaced by a single large opening performing the same functions.

Another form of auxiliary container is "shown in Fig. 4, in which the cavity 16 is substantially the same in form as those shown in. Figs. 1 and 2, although as in the outlet 17 from Q depression are replaced said passage "normal oil level of said container.
